I'd check the inside fuse panel as well, just in case.
If you were driving and it cut out then I'd suspect something that meters the fuel - injectors - and since the chance of them failing all at the same time is very small, I'd look at what controls those injectors: the ECU.
Do a reset. That's easy: take the negative lead OFF the battery, put your foot on the brake pedal, then go and put the lead back on (securely). Try starting again, make sure the glows get a chance to warm up first.
